Etching edges : In situ measurement by atomic‐force microscopy (AFM) is employed to investigate the dissolution of calcium phosphate crystals in the presence of different polymeric additives. The dissolution occurs in a way that is dependent on the pattern of functional groups on each polymer. The influence of poly(sodium)aspartate, polylysine, and serum albumins on the resulting crystal morphologies is discussed. The pictures show the dissolution of the (0 $\underline 1$ 0) plane of brushit in the presence of polyaspartate (the bar=1 μm).
